I have seen many techniques written on the package of Oil Pastel. From which, one technique is Sgraffito technique. It is basically done by covering the paper surface with light bright colours of choice & cover completely with a dark colour. Then Scratch patterns on it with Scratch tool.
I have also got one scratch tool, but not used that.
I tried something different.
First of all, I coloured with different colours in different places & then covered the surface with black colour. Then I used my Paper knife to make lines.
In this way, I did Line art on Oil Pastel. 😊
